CLAIM OF PRIORITY

This application claims the benefit of U.S. Provisional Application 62/589,782 filed Nov. 22, 2017.

FIELD OF THE INVENTION

The present invention relates to an apparatus with luer or similar fitting for use in atraumatically resizing biologic material.

BACKGROUND OF THE INVENTION

The attachment of a first structure with a male tapered fitting to a second structure with a conforming taper providing a female tapered fitting that is mateable to the first structure male tapered fitting, with a portion of the male tapered fitting of the first structure accommodated within a portion of the female tapered fitting of the second structure, such as the one described in U.S. Pat. No. 5,312,377 to Dalton, is widely used in the medical field to connect two liquid conduits end to end. These so-called luer fittings provide an ISO-standardized system (ISO 80369, “Small-Bore Morselizer Standards”, referencing ISO 594-1 and ISO 594-2 therein) across small-scale liquid fittings in order to make leak-free connections between two structures, such as a male luer fitting of a structure mateably attachable to a female luer fitting of another structure. These luer fittings are (i) common across medical and laboratory instruments to make leak-free/leakproof, mechanically secure connections between two parts, such as to join hypodermic needles to syringes or one catheter to another catheter; and (ii) described as having a male luer fitting and its mating female luer fitting, with the male luer fitting inserted into the female luer fitting and accommodated therein.

Often, such luer fittings are threaded to allow for a threaded attachment between structures with mateable luer fittings, which is commonly referred to as a “luer lock.” Such luer lock fittings are divided into two types called one piece luer lock and two piece luer lock or rotating collar luer lock. The one piece luer lock fitting comes as a single mold, with attachment of a structure with such a fitting to another structure with a conforming luer fitting achieved by rotating the entire fitting. In two piece or rotating collar luer lock, a free rotating threaded collar is assembled to the luer fitting and the attachment of a structure with such a fitting to another structure with a conforming luer fitting is achieved by rotating the collar. Alternatively, a structure with a luer fitting that is non-threaded can attach to another structure with a conforming luer taper dimension as that of the first structure, with the luer fittings of the conforming structures pressed together, with frictional forces holding the structures together. This is commonly referred to as luer slip or slip tip. The locking luer lock style luer fittings are generally more secure as one structure with an insertive luer (male) fitting is (i) inserted into another structure with a receptive luer(female) fitting and (ii) twisted to form a luer lock attachment, thus preventing accidental separation of the structures in addition to ensuring no liquids can leak through the attachment. Although not having a threaded attachment augmenting the frictional forces between the two attached structures, the luer slip style fitting allows for quicker attachment between two structures with complementarily sized luer fittings as the attachment simply requires a push of the structures together to form the attachment through the frictional forces between the structures.

In the cosmetic and plastic surgery field, fat injections, also known as fat grafting, are performed. Such procedures can be an effective way to reduce wrinkles, diminish acne scarring, and regain a more youthful appearance. By injecting harvested human fat, cosmetic and plastic surgeons can enhance facial fullness, fill deep creases, soften facial creases and wrinkles, plump up lips, and build up shallow contours. In order to be effective, fat particles injected into the face should be no larger than 1 mm in diameter.

The harvesting of fat with a cannula (a thin tube inserted into the fat tissue) is performed as a means of providing fat particles for injection. A common procedure for harvesting fat, also referred to as “lipoharvest,” is called the “Coleman technique” and involves a 2 to 3 mm diameter blunt cannula with a luer fitting attached to a 10-mL syringe with a luer fitting.

When injecting fat into a desired area, the diameter of the injection needle should be similar or slightly larger than the cannula opening(s) in order to avoid damage to the fat particles. In addition, to avoid any unnecessary skin damage when performing fat injection, it is desirable to be able to inject the harvested fat with very narrow-diameter needles, viz., 0.5 to 2.5 mm, to make only small diameter wounds in the skin. However, in order to harvest smaller particles that can pass through such needles, cannulas have been manufactured with smaller holes than traditional cannulas. Although smaller fat particles are obtained, the beneficial fraction comprised of the desirable stromal vascular fraction (SVF) containing a large population of regenerative cells called adipose derived regenerative cells (ADRCs) comprised in part of fibroblasts and stem cells.

As such, it is desirable to harvest larger particles containing the SVF and have a device that allows for atraumatic resizing of the relatively large harvested fat particles without loss of the beneficial SV fraction, while not losing sight of the need for smaller particles to ensure survival until the new blood supply is established to allow for the injection of effectively-sized fat particles (viz., no larger than 1 mm).

Referring to FIGS. 1-9, morselizer 10 comprises a hollow structure, preferably a thin-walled cylinder, with an inner wall I and an outer wall O and extending axially from a first end and a second end (i.e., the cylinder flat surfaces or bases), wherein both ends are open. Morselizer 10 can be made of any one or more materials known in the art, such as glass, preferably laboratory-grade glass; metal; or plastic, preferably a plastic impervious to and non-degraded by aqueous and organic solutions.

With reference to FIGS. 1-7, morselizer 10 is comprised of first end section 12, second end section 14, and center section 16 extending axially between first end section 12 and second end section 14. The axis of morselizer 10 provides an axial liquid pathway along the hollow structure thereof, extending from first end section 12 to center section 16 and then to second end section 14. Preferably, the inner diameter of morselizer 10 is axially continuous, with the inner diameters of each of first end section 12, second end section 14, and center section 16 the same. Morselizer 10 can have an inner diameter of any size capable of being complementarily sized to structures with small-scale liquid fittings, preferably in the range of 0.1 mm to 10 mm, more preferably in the range of 2 to 5 mm, most preferably in the range of 3 to 4 mm, with an outward bevel extending from center section 16 to first end section 12 and second end section 14.

With reference to FIGS. 1-7, each end section 12/14 of morselizer 10 comprises an axially and radially hollow luer fitting that is attachable to a structure with a complementarily sized luer fitting. The attachment of the morselizer 10 at the each of the end sections 12 and 14 comprising a luer fitting to a structure containing a substantially liquid solution with substantially solid materials suspended therein and having a complementarily sized luer fitting prevents any solution leakage out of the structure during material flow from the structure to morselizer 10.
